Application July 19,1946, SerialNo. 6841849 1 Claim.

This invention relates to 1?.W, and useful inrprovementsand' structuralrefinements in brush attachments for collapsible tubes, and theprincipal object of'the invention to provide a device of the characterherein described, such as may be conveniently and elfectively employedas an applicator for shaving cream, shoe polish, and the like.

A further object of the invention is to provide a brush attachmentwhich, in addition to its primary purpose as above described, will alsoconstitute a self-sealing closure for preventing the contents of thetube from drying.

Another object of the invention is to provide a brush attachment whichmay be readily applied to and removed from the collapsible tubes withwhich it is employed.

An additional object of the invention is to provide a brush attachmentwhich is simple in construction, convenient in operation, and which willnot easily become damaged.

A still further object of the invention is to provide a brush attachmentwhich will readily lend itself to economical manufacture.

With the above more important objects in view and such other objects asmay become apparent as this specification proceeds, the inventionconsists essentially of the construction and arrangement of parts asshown in the accompanying drawings in which:

Figure 1 is a cross-sectional view of the invention, showing the same asapplied to a collapsible tube.

Figure 2 is a side elevation of the collapsible tube per se.

Figure 3 is a perspective view, partially broken away, of a perforatedcap used in the invention.

Figure 4 is a cross-sectional view, taken substantially in the plane ofline 4-4 of Figure 1, and

Figure 5 is a side elevation of the brush attachment per se.

Like characters of reference are used to designate like parts in thespecification and throughout the several views.

Referring now to the accompanying drawings in detail, the inventionembodies in its construction a substantially cylindrical body It) formedin one end thereof with a screw threaded bore II and with a counter-sinkl 2, this being adapted to receive the screw threaded neck portion I3and the frusto-conical shoulder M respectively of a collapsible tube I5.The later is, of course, of conventional design and is illustrated inthe accompanying drawings for reference purposesvenient manner in theremaining end ofabody it, for which purpose the body is formed with asubstantially circular recess H, as will beolearly apparentfromtheaccompanying Figure 1.

Itwill be also noted that the portion of the body It adjacent thebristles I6 is of a somewhat reduced diameter as at I8, thus forming anannular shoulder Hi, the purpose of which will be hereinafter more fullyexplained.

An axially disposed rubber tube 20 is formed at one end thereof with anout-turned flange 2 I, whereby it may be rigidly secured in the body I 0by means of a suitable insert 22 which is pressed into theaforementioned bore l1. It will be noted that the bristles IS, ineffect, are secured in this insert, as is best shown in Figure 1.

The insert 22 is, of course, provided with a central passage and acounter-bore designated collectively by the reference character 23, inorder to accommodate the tube 20 and the associated flange 21.

The remaining end portion of the tube 20 extends into the bristles I6and terminates in a closed extremity which is provided with a pair ofnormally closed openings 24. When the invention is placed in use, theconventional cap 25 is removed from the threaded neck portion l3 of thetube l5 and the tube is applied to the body III as has already beendescribed, and as is best illustrated in Figure 1. It will be noted inthis connection, that the diameter of the body It) is substantiallyequal to the diameter of the tube, whereby the body will constitute whatmay be referred to as a continuation of the collapsible tube.

As pressure is applied to the tube l5, the con tents thereof will beforced into the rubber tube 20, thus causing the opening of the slots oropenings 24 and discharging the contents of the tube into the bristlesIt. The advantages of the invention will thus become clearly apparent.

When the invention is not in use, the relaxation of the pressure uponthe tube l5 will be accompanied by a corresponding relaxation ofpressure of the contents of the feed tube 20. In this manner, theopenings 24 will be automatically closed by the inherent resiliency ofthe tube 20.

A removable cap 25, opened at one end thereof and provided at itsremaining end with a plurality of perforations 26, may be positioned onthe portion l8 of the body In in order to preserve the brush attachmentin a sanitary condition. In this connection, it will be noted that theaforementioned shoulder l9 provides an effective seat or stop, to limitthe extent to which the cap 25 is inserted upon the body [0.

It is believed that the advantages and use of the invention will beclearly understood from the foregoing disclosure and accordingly,further description thereof at this point is considered unnecessary.

While in the foregoing there has been shown and described the preferredembodiment of this invention it is to be understood that minor changesin the details of construction, combination and arrangement of parts maybe resorted to without departing from the spirit and scope of theinvention as claimed.

What I claim as my invention is:

A brush attachment for collapsible tubes having a beveled end portionand a threaded outlet neck carried by said beveled end portion, saidattachment comprising a cylindrical body having a beveled sealing seatat one end for engaging the entire outer surface of the beveled endportion of a collapsible tube, a recess formed at the opposite end ofsaid body, said body having an axial internally threaded borecommunicating with said seat and said recess, an insert mounted withinsaid recess. a tuft of bristles carried by said insert projectingoutwardly from said recess, and an axially disposed resilient feed tubecarried by said insert, said tube having a flange at one end, saidinsert having an inner face contacting the inner wall of said recess,the inner face of said insert having a depression therein receiving saidflange, said flange surrounding said bore and bearing against the neckof the said tube to which the body is attached, the remaining end ofsaid feed tube extending into said bristles and terminating in a closedextremity having a plurality of slits therein.
